We would want to change the owner write permission bit for all executables. In 
F-12 we took care of the major directories, this is phase 2 of the same 
project where we take a bigger step. Phase 1 was proving that the missing 
write permission on directories won't mess up system updates. Phase 2 would do 
the same to files.

Yep.

Nope. You can change them all on your system right now if you want.
